Corgi AA27502 Short Sunderland MK3 ML788/2-S, No.422 Squadron RCAF, Pembroke Dock

The Short Sunderland Mk.III proved to be the definitive version of what was the RAF’s largest aircraft of the War. As the electronic detection of enemy U-boats became essential in disrupting their operations, the earlier stickleback radar antennas on the spine of the aircraft were replaced with the later and more capable ASV. MK.III units, which were housed in streamlined blisters underneath each wing, outboard of the floats as modelled here. As U-boats could now detect approaching RAF aircraft with their own radar sets, these new radar blisters operated outside the frequencies used by the previous units and ensured that Coastal Command Sunderlands continued to keep marauding U-boats fearful of attack from the air.

The sight of large numbers of these impressive flying boats operating from RAF Pembroke Dock must have been awe inspiring for anyone lucky enough to witness it. At one time, this was the largest seaplane base in the world, this Welsh coastal town was to become crucially important in the Battle of the Atlantic.
